A del.icio.us idea ...

We talked about this in class on Thursday. Students often find more, and better, sites than I do. You're better websurfers than I am. ;-) That got me thinking .....

I spend a lot of time looking for good websites that help us learn in this class. But what if we all spent a little time doing that? What if there was an easy way for us to both save our bookmarks (without cluttering up our favourites list) and share them with the whole class with the click of a single button? And what if we could access those bookmarks not just from home, but from any computer in the world? Hmmm .....

Well, there is an easy way to do that! Instead of saving bookmarks on your home computer sign up for a free account at a site called del.icio.us. You can then access them from any computer in the world. You can easily install a little button/bookmark that allows you to save any webpage you're looking at without interupting your surfing. Now we can all make recommendations to each other learning resources with the click of a single button in our del.icio.us accounts! Tag it using this tag:

You should also tag each entry with several other words that indicate what it is about; things like: trig graphing stats circles etc. Also, include a brief descriptive clipping from the site (or type one in yourself).

As soon as someone starts saving links I'll add a del.icio.us box to the bottom of the sidebar of our blog. It will show the 10 most recently saved links automatically as you find them. There is will also be a link to the entire archive that you can browse at your leisure.

You can read this tutorial on how to get started with del.icio.us. You might also be interested in watching this screencast that illustrates just how powerful this web tool is.

Remember, this is part of your homework for Spring Break. You must save at least one link for each unit we have studied so far. Try not to post a link that someone else has already found. You can see what's already been posted by looking in our archive.

BoB = Blogging on blogging.

Teh = Typo, oh so fun, maybe intentional?

Anyways, I'm just having trouble remembering all the identities, and that's about it.

Since the test is on Friday so we have to do this again.This unit is pretty easy to me because this stuff is more on algebra which i like in Math. So yeah!! I like this unit I hope we all do good in the test. A tout à l'heure.

Box Up Sunday!

This is a clever little game. You've got to get the small blue box inside the large red box. You can only push a box from the inside. The black boxes, if used cleverly, can help you get the blue box inside the red one. But sometimes they're just in the way. I made it to level 4 pretty quickly, but then it starts getting tough. How far can you go? ;-)

Have fun with this!

Seek and ye shall find ...

The Coin Hunt has officially begun as of 12:30 this afternoon. The race is on! Who will be the first to find the coin? Will the students find their coin before the teachers find theirs? Who will win the pizza party? Which charity will benefit from this year's hunt?

Check the walls of the building as you walk into school in the morning for hints to figuring out the puzzles.

Happy π Day!!
Have fun with it. ;-)

Scribe #22

Hey guyzzz.... It's me again, Emile your scribe for Friday, March 10,'06. The first part of the class in the morning, we had a debate about what time would be the test? The majority decided that we held the test in the afternoon.

After the class debate, Mr. K asked us, if we have any question involving any topic in transformation and word problems. Some of our classmates asked about the even and odd functions. Here are some examples:

An example of even function:

f(-x)= f(x)

f(x)= 2x²-4

f(-x)= 2(-x)²-4
f(-x)= 2x²-4; It is an even function because f(-x)=f(x).


An example of an odd function:

f(-x)= -f(x)

f(-x)= (-x)³-(-x)
f(-x)= -x³+x

-f(x)= -(x³-x)
-f(x)= -x³+x; In this case it is an odd function because f(-x)= -f(x).


Another issue was brought in and it was the reciprocal function or 1/f(x). And it was like this:

f(x)= 2x²-4

Then half part of morning of the class we wrote something in our Math Dictionary about:


The other Trig Functions

The Tangent Function

f(x)= tanx
















Properties of the Tangent functions

Domain:{xlx is not equal pi/2+kpi; k is an element of I, x is and element of R}
Range: (-00,00) or {yly is an element of R}
Amplitude: undefined
Period: pi
Roots: kpi ; k is an element of I



The Cosecant Function

f(x)=cscx= 1/sinx

Properties of the cosecant function:

Domain: { xlx not equal k pi; kis an elemnt of I, x is an element of R}
Range: (-00,-1] U [1,00)
Amplitude:undefined
Period: 2pi
Roots: none
y-intercept: none
Symmetry: an odd function


That's all for me now. Oops! before I forget the next scribe is Teddie. A tout à l'heure.

The Mystery Coin Hunt!

π Day is around the corner .. it's five days away! Soon, soon, the hunt will be on!

Somewhere on the property of DMCI a coin will be hidden. Hidden so carefully and cleverly that it cannot be discovered by chance or simply by looking for it. On March 14, π Day, the coin's location will be revealed buried in a series of riddles and puzzles. Until it is discovered the coin's location will remain a mystery....

As this unit comes to an end, the thing that I just find it hard, well not hard... sort of hard was doing the expansion and compression, although Alridge taught me some of it, I sort of get it now. But when the expansion or compression, reflection and translation are all in one equation I just don't get it from that time on...
All in all this unit is lot easier than the last unit that we had... A tout à l'heure and Au revoir

Sunday Gridlock

In this game you have to move the blocks (vertical blocks move only vertically and horizontal blocks move only horizontally) out of the way so that the blue block can slide out the "door" on the right. Although this game can sometimes get frustrating there is always a way out. Remember Sisyphus!

So far I've made it to level 6, how far can you get?

It's Coming ...
